To all whom it may concern: 7

Be it known that I, LEON BLocH, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in a Combined Waste and- Overflow, of which the following is a specification.

This invention relates generally to the class of baths and closets but more particularly to a combined waste and overflow wherein it is often desirable and sometimes necessary in lavatory construction to conceal the major part of the fitting.

An important object of the invention resides in the provision of a concealed waste pipe provided at its point of connection with the tub or basin, as the case may be, with a valve chamber, a valve movable in said chamber, and an exposed connection at the opposite end of the pipe which is designed to permit the valve to be entirely wlthd'rawn from its chamber and the waste pipe without the necessity and expense of in uring the wall structure or conceahn surface with which the device is associate Another object of the invention pertains to the provisionof a valve operating in the waste pipe, a connection-at t e exposed end of the waste pipe, and a valve actuating mechanism assoclated with said connection and with the valve and constituting such part of the latter as to enable such parts to be removed together from their normal positions and thou h said connection.

A still further ob ect of the invention resides in a novel combination of parts for facilitating-the normal closin of the waste opening, while permitting 0 an uncovering of the opening as the occasion necessitates.

Another object of the invention pertains to the provision of a combined waste and overflow which will include a gravitationally operatin valve, and novel mechanism for moving the valve in one direction, the valve and said operating mechanism being substantially a unitary structure and arranged whereby the parts in their entirety may be removed when it is desired to repair a worn valve or replace the same or clean the valve.

With the above and other objects in view vention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described andparticularly pointed out in the claims.

In the accompanyin drawing, has. been illustrated a single an preferred form of the invention, it being, however, understood that no limitations are necessaril made to the precise structural details t erein exhibited, but that changes, alterations and modifications within the scope of the claims he resorted to when desired.

igure 1 IS a vertical section through the combined waste and overflow showing the valve opened.

Fig. 2 is a horizontal section through the valve.

Fig. 3 is a front view of the locking lever.

In practice use is made of a T'shaped valve chamber 10 having a branch connection 11 adapted to open to the waste ordischarge connection of a sink, tub, basin or the like, and as illustrated, said chamber is provided at a point directly below the branch 11 with a flared valve seat 12. The lower end of the valve chamber is open as shown and designed for connection with the usual well known soil pipe. Rising from the opposite end of the valve chamber is an overflow pipe 13, which is suitably secured in any well known manner to an el-' bow 14, the same being bulged internally to provide a chamber or space which opens to the front of the elbow as clearly illustrated in Fig. 1. The bulging of the walls of the elbow, while being prlmaril designed to permit of manipulations of t e waste valve therein, is also peculiarly constructed so that the inner walls of the. elbow serve as smooth deflecting surfaces for a purpose to be presently explained.

The front open end of the elbow is adapted to be positioned against the outer face of a bath tub, basin, sink or the like in line with the discharge opening 15. At the opposite side of the discharge opening 15 is an escutcheon 16 having discharge opening 17 therein of suitable well known design. The escutcheon and the elbow 14 are positioned with respect to each other so that the wall of the tub, basin, sink or otherwise containing the openin 15 may be sandwiched and clamped there tween. In order to permit of an effective clamping of such parts, use is made of a threaded rod 18 having one end detachably accommolatter may be freely seated in t dated in a boss 19 in the elbow, while adjacent to its opposite end said rod is opera: tively accommodated in the central portion of the escutcheon. the rod is provided with a short extension 20. e \p Mounted to move vertically in the valve chamber 10 and also in the waste pipe 13 is a cylindrical valve 21 having a frusto-conical base 22 adapted to engage-with the valve I face 12 when the valve is closed. The valve is provided preferably with an internalweight" 23 to accelerate the closing of the valve. The valve is hollow throu hout and it is preferably; provided at its. si es with a vertical series of perforations 24 adapted to interchangeably accommodate a supporting bail 25. This bail is connected in some suitable well known manner with the lower end of a relatively flexible controlling wire or connection 26. The upper end of the connection is pivotally connected at 27 to a rocker 28 which swings from supporting ears 29 carried by the escutcheon. Forwardly of the supporting ears the rocker is provided with a cylindrical extension 30 on which is rotatably mounted a valve lockin lever 31. This leverma be constructed 0 porcelain and it is provided with a handle portion 32 and a cam portion or head 33, the latter having curved corner surfaces 3434 which merge into a central recess 35. The cam portion of the lever underlies the cylindrical extremity 20 of the rod 18 and the curvatures 34 of the cam portion are'adapted to freely pass over said extremit so that the be receiving recess 35. In this position it will be understood that after the rocker 28 is adjusted to the position shown in full lines in Fi 1, said extremity 20 and the cam portion 0 the lever 31 will be brought into co-acting relation and the valve 21 held in a raised or opened position. At this time, the waste water will find its esca e past the valve.

tirely withdrawn. This arrangement is par-- ticularly desirable where the connections are concealed behind the fixture. It prevents the necessity of having to dismantle the Beyond the escutcheon hidden elements of the fixture, while greatly facilitating the operation of repairing or cleaning the valve as will be understood.

What is claimed as new is 1. A combined waste and overflow comprising a valve chamber having means for connection with a waste opening, a pipe leading from said chamber, an overflow connection operative] associated with said pipe, an elbow attache to the pi e, a valve movable in; said chamber for cibsing the waste opening andmeans for permitting said valve to be moved through the pipe and withdrawn from said elbow.-

2. A combined waste and overflow comprising a valve chamber having means for OQIlIlGOtlOIl Witll a waste opening, a. pipe leading from said chamber, an overflow connection operatively associated with said pipe, an elbow attached to the pipe, a valve movable in said chamber for closing the waste opening, means for permitting said valve to be moved through the pipe and withdrawn from said elbow, said means consisting. in proportioning the vertical depth of the elbow with regard to the length of the valve, an escutcheon removably fitted against the open end of the elbow, and mechanism carried by the escutcheon for operating said valve.

3. A combined waste and overflow comprising a valve chamber, an elbow, a pipe between the elbow and valve chamber, a member extending over the open end of the elbow, and detachably connected therewith, a

valve movable in the pipe and in said valve chamber, said valve being open throughout in vertical line with the pipe and said valve chamber, the elbow and said valve being relatively proportioned so as to permit the valve to be moved through the elbow and withdrawn from the'pipe, as and. for the purpose described. i v,

4. In a structure of the class described, an elbow, a pipe connected with one branch of said elbow, a valve slidable in said pi e, a valve seat located below said pipe and a apted to co-act with said valve, an escutcheon extending over the branch of said elbow, means or detachably connecting said escutcheon with said elbow, the internal diameter of the elbow proportioned with regard to the size of said valve to permit the latter to be removed through the elbow when the escutcheon is removed, and a flexible valve-actuating-connection leading to the valve and having a manipulating terminal ex osed from said elbow. is

n testimony whereof I have afiixed my signature.
